To aZZ whom it may concern:

Be it known that l, FRANTZ ldonrnNsnN, a subject of the King of Denmark, and resident of l-lelsingfors, Finland, have in-- vented a new and improved Arrangement for Separators with Hanging Bowls, oi which the following is a full, clear, and exact description.

In separators with suspended bowl it usual to suck the new milk into the bowl by a suction device placed in connection with the latter, for instance, by wings "his tened to the bowl and working as a suction fan. The milk is then conveniently sucked from a milk vessel placed under the bowl through a nozzle at the lower part bowl and then through a channel suitably arranged close to the spindle, w'ierelrom it is forced into the bowl at the upper end of the channel by centrifugal force.

In separators of this kind hitherto used the air channel leading from the mentioned milk channel to the suction device is usually placed so close to the inner level of the milk in the bowl, that the liquid not infrequently is caught by the air cur; nt and thrown out through the suction The present invention has the purpose 0 preventing this trouble and consists to that effect mainly of an arrangement in wine apertures are leading from the milk channementioned above and from the suction de vice approximately toward the center line of the bowl to space near the center line.

A. way to carry out the invention is illus trated on the drawing which shows the rangement partly in vertical section, applied to a separator of the kind mentioned above.

The spindle 1 carries on its lower end the bowl 2, to the lower part out which a nozzle 3 is fastened, submerged in a milk vessel The milk is sucked from the milk vessel through the nozzle 8 by an arrangement as described below,'and enters through opening n the channel 4i arranged close to the spindle, for instance in connection with a center tube, and flows then from an outlet at its upper end 5 into the bowl. The neck of the bowl is provided with openings and b and in the lower part or the bowl is a division plate 0 extending into the neck and forming with the bowl passages for the skimmed milk and cream. The skimmed milk is discharged through the opening a into the pan (Z having a discharge about (Z and the cream through opening Z) into the Specification of letters Eitent.

pan 6 having the discharge spout e The device creating the suction of the milk con sists of the wings 7 fastened between the top 01 the bowl and a co plate 6; during the rotation of the bowl the wings are working in the same way as a suction fan, the suction extending itself through a channel 8 in the bowl nave 9 to the space 10 between the nave 9 and a thinner part 11 01": the spindle 1 and therefrom to another channel 12 which is in connection with the space 10 and the milk channel a.

The intermet iate space or air channel 10 is thus placed so close to the center of the separator bowl that the centrifugal force acting on the milk at the outlet 5 or the channel t is able to overcome the suction acting in the opposite direction through the channels 8, i0 and 12. In this way any part ot the liquid is prevented from being sucked through the channel aid thrown out through the suction "fan. carrying out the invent-ion as shown on the drawing the placing of the air char el near the center has been achieved by making the separator spindle l thinner the part 11. Further more, by this, a practical and easily accessible arrangen ent of the suction channels as well as a perfect guide of the bowl on the spindle and a conveni nt suspension of the bowl are attained.

However, the same object can be achieved in otner ways than shown on the drawing, without departing from the idea in the invention, for instance, by an extension of the bowl nave, while the thickness of the spindle remains unchanged, or by making an extension of the nave and the same time inclining the spindle.

As it appears from the drawing. only the suction arrangement is placed at the top of the bowl, while the inlet for the new mill: is placed at the lower part of the bowl. l-iere tne cream and the skim milk outlets are also conveniently placer", through which complete freedom with regard to position and dimensions of the suction space 10 and its apertures is attaineo, without taking the above named in and outlets into considera tion.

Claims:

1. separator of the type having a suction fan for drawing in milk, andhaving an aperture through which cream is driven due to the separating action of centrifugal force, and characterized by having an outlet at one draw the milk into the suction fan.

2. In a separator, a bowl, a suction device on the top of the bowl, a suction tube extending from the top of the bowl through the bottom thereof, a longitudinal tube com municating with the suction tube and having an outlet at its upper end discharging into the bowl, and means for establishing communication between the suction device and said tube, said means being substantially at the center of the bowl.

' 3. In a separator, a bowl, a suction device on the top of thebowl, a suction tube leading from the top of the bowl through the bottom thereof, and a spindle in the upper end of the tube, a longitudinal tube communicating with the suction tube atits lower end and having at its upper end an outlet dis'charg ing into the vbowl, "the spindle and "suction tube being formed with a passage communieating at the upper end with the suction devlce and at its lower end with the said channel,

opening in the lower end of the channel and the other two leading from the ends of the said passage, one establishing communication between the passage and the suction device and the other establishing communication between said passage and the channel.
